CAR-'COUPLING.

SPECIFICATION forming part Of Letters Patent No. 261,328, dated July 18,1882.-

Application filed January 30, 1882. (No model.)

To all whom it may concern Be it knownthat I, WILLIAM LIVINGSTON FISHER,of Bay City, in the county of Bay and I State of Michigan, have inventeda new and useful Improvementin Car-Couplings, of which the following isa full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l is a plan view of my improved carcoupling, part beingrenioved,and partly in section. Fig. 2 is a sectional side elevation of the same.Fig. 3 is a side elevationof a part of the same. Fig. 4 is a frontelevation of a part of the same. Fig. 5 is a side elevation of theforward end of the upper part. Fig. 6 is a view of the under side of theupper part, partly in section.

The object of this invention is to facilitate the coupling of cars andpromote security in the use of car-couplings.

The invention consists in a car-couplin g constructed with a lower partrecessedin its upper side and the upper part fitted into-the recess inthe lower part and having its'jaw a littlein the rear of the lower jaw;and,'also, in the combination, with the recessed shoulder of the lowerpart, of the lugs formed upon the forward shoulders of the upper part,whereby the vertical playof the upper part of the coupling is limited,as will be hereinafter fully described.

The couplinghead is formed in two parts, A B, the lower part,A,of whichis rigidly connected with or formed solidly upon the drawbar 0. Themiddle part of the upper side of the part A is cut away to receive theupper part, B, the said recess having .vertical shoulders at its forwardand rear ends, as shown in Figs. 1 and 3. In the rear shoulder of thepart A is formed a slot, D, to receive a tenon, E, formed upon the rearend of the part B, and in the forward shoulder of the said part A isformed a slot, F, to receive a tenon, G, formed upon the forward end ofthe said part B. The part B is hinged to the part A by a pin, H, whichpasses through the said part A and through the tenon E of the part B.The lower side of the end of the tenon E is beveled, as shown in Fig. 2,to allow the,forward end of the said part B to have a slight upwardmovement. 7

Upon the forward shoulders of the part B, at the opposite sides of thetenon G, are formed lugs I, which enter recesses Jin the forwardshoulder of the part A. The recesses J are made deeper than thethickness of thelugs I to allow the forward end of the part B to have aslight vertical movement and to limit the said movement.

The mouth ofthe coupling-head is made hopper-shaped, as shown in Fig. 4,and the upper and lower inclines are so formed thatthe lower jaw, K,shall be a little infront of the upper jaw, L, which is formed upon theforward end of the tenon G. The throat of the coupling,

or the space between the jaws K L, is made a little higher than thethickness of the couplinglink M. By this construction the said jaws willhold the link in a horizontal position, so as to enter the coupling-headof an adjacent car when the cars are run together. The link M is held inplace by the coupling-pin N,which passes through the tenon G and throughthe part A. When the coupling is under a draftstrain the forwardshoulders of the part B abut against the forward shoulders of the part'A, so that the couplingpin N will be firmly supported above and belowthe link M.

0 is a stirrup, which is placed in a recess,P,

in the parts AB,in the rear of the jaws K L, and its arms pass up intorecesses formed in the opposite sides of the tenon G, and are pivoted tothe said tenon a little in front of the hole for the coupling-pin N byapin, Q. With this construction the stirrup 0 will rest against theinner side of the pin N when the said pin is in place, and when the pinN is raised will swing forward beneath the lower end of the said pin, soas to support the said pin in a raised position, the stirrup restiu gagainst the inclined lower side of the recess P, so that when thecarsare run together the entering link M will strike against the stirrup Oand push it back, allowing the pin N to drop through the link M. Withthis construction the slight Vertical movement of the upper part, B,ofthe coupling, in connection with the recess P, al-

lows the link M to have the necessary play, I and allows high and lowcars to be coupled when required.

Having thus described my invention,I claim as new and desire to secureby Letters Patent 1. An improved ear-coupling head, consisting of thelower part, A, having its upper side recessed and provided with theslot: F, and the upper part, B, provided with the tenon G and fitted inthe said recess and slot, and having its jaw L a little in the rear ofthe lowerjaw, K, substantially as and for the purpose set; forth.

2. In a car-coupling, the combination, with the recessed shoulder of thepart; A, of the r 5 lugs I, formed upon the forward shoulders of thepart B, substantially as herein shown and described, whereby thevertical play of the upper part of the couplingis liinited,as set forth.

WILLIAM LIVINGSTON FISHER.
